Jurisdictions across North American continue to transition beyond ASHRAE standards for exterior wall assemblies, instead adopting a more comprehensive building energy performance standard (BEPS) approach to envelope design.
This shift brings advantages like increased design flexibility and reduced operating costs, but it also calls for a rethinking of how these wall assemblies are constructed. Instead of relying on traditional line-by-line methods, the performance of individual components must be considered along side their overall impact on the entire high-performance exterior walls assembly.
This webinar will explore the role of thermal bridging in meeting new BEPS, as well as ASHRAE standards. It will cover common insulation methods—including interior, split, and exterior applications—and present strategies to minimize thermal bridging through different cladding attachments. The session will conclude with real-world case studies that highlight the importance of an integrated approach to component performance in achieving optimal results.
LEARNING OBJECTIVES:
- Gain an understanding of emerging Building Energy Performance Standards (BEPS), and compare their key similarities and differences with ASHRAE standards.
- Explore how highly conductive wall components affect the overall effective wall R-value in a non-linear manner.
- Review common cladding attachment systems by comparing factors such as cost, thermal performance, constructability, installation efficiency, and fire resistance.
- Review the Cladding Support Components and Systems Product Category Rule (PCR), which govern Environmental Product Declarations (EPD) for cladding attachments
- Understand the real-world impact of various exterior wall assembly methods on project outcomes.
